摘要：
A hybrid stent (100) includes at least one resilient ring (105) comprising a superelastic wire (102) formed in a sinusoidal pattern of alternating crests (110) and troughs (115) about a circumference of the ring (105). A plurality of malleable cannula segments (120) overlie the superelastic wire at the crests and troughs. Each of the cannula segments (120) includes a bend (125) and has an inner diameter sized to allow relative motion between the wire (102) and the cannula segment (120). The hybrid stent (100) may also include a plurality of gaps (130), where each gap (130) is defined by a spacing between opposing cannula segments (120). Deformation of the malleable cannula segments (120) dominates a response of the stent to substantially uniform radial forces, and deformation of the resilient ring (105) dominates a response of the stent to radially nonuniform crushing forces.
